The US company usually releases iOS updates every few months, which also reach all compatible devices in the blink of an eye, something other systems like Android or Windows Phone cannot say. Redmond Pie
Normally, when Apple releases a new version of the system it fixes the bug that made the jailbreak possible and users who upgrade must wait again. Although most of them prefer to wait and not upgrade to the latest version in order not to lose the jailbreak.
To avoid the latter, Apple has made the updates automatic in the latest versions of iOS , so if you press where not the device starts updating automatically at night without you noticing. However, there is a tweak that can be very helpful to prevent iOS 9.3.4 from installing on your iPhone or iPad.
Previously, the software used to do the jailbreak was able to automatically block detection of a new system update, so there was no need to worry. But it seems that Pangu’s guys don’t have that feature in their software and more than one user has lost the jailbreak .
If you have your device with the jailbreak done and you want to avoid an upset like this there is a tweak that you can’t miss. This is mikoto, a tweak that allows you to block the system update check which is available at https:/cydia.angelxwind.net repo.
You have to add this repo to Cydia in order to download the tweak mikoto. Once installed, reboot the device and go to the tweak settings in the Settings menu, where you have to activate the “Software Update Disabler” option .
This will ensure that updates via OTA (Over The Air) are not displayed on the device . This way you don’t run the risk of losing the jailbreak unintentionally, as the latest version of iOS will not be installed unless you do it manually.
